Features: brand new and high quality High performance. Low cost. Small package. Flexible I/O connects RP2040 to the physical world by allowing it to speak to almost any external device. High performance breezes through integer workloads. Low cost helps ease the barrier to entry. This isn'for t just a powerful chip: it's designed to help you bring every last drop of that power to bear. With six independent banks of R AM, and a fully connected switch at the heart of its bus fabric, you can easily arrange for the cores and Dma engines to run in parallel without contention. RP2040 builds Raspberry Pi's commitment to inexpensive, efficient computing into a small and powerful 7 mm 7 mm package, with just two square millimetres of 40 nm silicon. Specifications: Dual-core Arm Cortex-M0+ processor with flexible clocks running up to 133MHz. 264KB on-chip SRAM. 2 UARTs, 2 SPI controllers, 2 I2C controllers, 16 PWM channels. 1 USB1.1 controller and PHY, supporting host and device. 8 programmable I/O (PO) state machines for custom peripheral support. Supported input power 1.8-5.5VDC. Operating temperature -20C to +85C. Drag-and-drop programming via USB with mass storage. Low-power sleep and hibernate modes. Accurate on-chip clock. Temperature sensor. On-chip accelerated integer and floating-point libraries. Note: No retail package. Please allow 1-3mm error due to manual measurement. pls make sure you do not mind before you bid.
